Our Carbon Fiber tubes are designed for the best strength to weight ratio. We use a full wrap of 3K filament fabric impregnated with strong clear epoxy, then a fine gloss or matte finish is added. There are no fillers! These CF tubes provide a perfect balance between strength, stiffness and weight. This design creates a very light tube, strong enough for Multi-copter design and their numerous crashes. Also the twill design prevents damage from twisting of the tube, enabling these tubes to handle heavier loads. These tubes are very different from the common "kite" tubes.

Other advantages include handling the pressure of motor blocks, preventing rotation failure and crushing of the arm material common in multi-copter drone builds.

Discount pricing for large quantities can be arranged by contacting us. Also custom CF tubes can be manufactured for our customers when in LARGE quantity. This would include custom O.D., I.D., length and drilling of needed holes or slots.

What is a 3K Twill Carbon Fiber Tube?

Carbon fibers are known for their high tensile strength
(stretch/pull). The threads
are very small and are normally bundled together to make a stronger “rope”
called a tow. A common tow in this application uses 3000 fibers (called 3K). Even
though a tow may contain 3000 carbon fibers it is still small. These tows are woven together in a crisscross
pattern to form a very thin fabric sheet.

The term “Twill” refers to the pattern of the weave which is
more complex than a simple 1x1 weave pattern.
Common twill weaves may include 2x1, 2x2 and 3x1 patterns. These patterns have proven to be stronger
than 1x1 weaves. FlyCarbon
commonly uses a 2x1 twill weave.

The manufacturer will use a light weight clear epoxy to
impregnate the weave to hold the carbon fiber in place as it is formed into a
round tube. The epoxy adds some strength to the tube; but its main job is to spread the load evenly over all the fibers
for maximum durability. Lastly, a very thin spray coat is applied to produce a gloss or matte finish.

(Many “cheap” carbon fiber tubes found online will use
material other than carbon, such as fiberglass fibers.
Some produce tubes with paper that have a twill pattern on it.)

FlyCarbon's carbon fiber tubes have been used in
high end drone assemblies, marine and aircraft applications. We are proud to offer simple high quality
products at a discounted price.

How to Cut Carbon Fiber Tubes?

To cut them well Carbon Fiber tubes require the right tools. First it requires protection for your eyes and a mask to prevent inhaling the carbon dust. It is also recommended to have a vacuum system near the cutting area to reduce the dust in the air. A high speed cutting tool is best (such as a Dremel tool), use a metal cutting blade. Another useful tool can be a high RPM router with a narrow diamond cutting tip. In both cases it may be best to mount the tool on a jig and then rotate the tube through the blade.
